"He's an unusual fellow. I've never met anyone quite like Jay. And I will say, and I'm happy to say, that I think he is the funniest guy I've ever known.

Therefore, the fact that he is also maybe the most insecure person I have ever known -- I could never reconcile that."
-- David Letterman, talking to Oprah Winfery, about his rival talk show host Jay Leno.
